Hendersonville refused to give the federal government a certificate of occupancy for its new ICE office. ICE representatives had told the county the building, located in an area zoned only for office space, was office space. But it alarmed neighbors with its scary fence topped with barbed wire. While assessing the site, city inspectors found a detention area, which had not been disclosed in the site plan, and detention is not a use by right in office zonings. ICE must now decide how it will resolve the building’s nonconforming feature.
